FILLER.

. 1 Application filed August 30, 1926, Serial No. 132,545. Renewed May 9, 1927.

' tion of the structure in which the rails are imbedded, and for otherwise improving the installation and maintenance of tracks and adjoining paving structures.

Briefly, my invention hasrto do with a socalled preformed rail filler, its fabrication and application to the rail being well illustrated in the accompanying drawing, in which Figure 1 is a perspective view of a rail section illustrating the filler proposed by the present invention applied to both sides thereof.

Figure 2 is a detailed perspective view of a section of the rail filler; and

Figure 3 is a perspective view of a'section of rail of the flange type illustrating the application of the filler to one side thereof.

Referring now to the drawing in detail. Ordinary or conventional types of track rails have a head A, base B, connecting web C, with a space between the head and base. Itso happens when a rail, for instance in city streets, is imbedded in the paving structure the paving material usually intimately contacting with the rail, filling in the space between the head and base, consequently leaving] no chance for the sound'of the cars 1 passing over the track to be mufied or deadened,- then again expansion and contraction not being provided for is apt to crack the pavement.

According to my invention instead of permitting the paving structure in which the rail is imbedded to contact with the paving material, I propose to fill the space on one or both sides of the. web C with material suitable for the purpose, which for the most part will be some readily compressible material, such as, asphalt mixed with fibrous material, such as, felt, sawdust, corn cob fibre, roofing scrap, or the like, the idea being to makeup a soundproof, preformed,

blocklike strip, extruded or otherwise molded to fit the space between the head A and base B, as best shown in Figures 1 and 3.

in thisparti'cular case I am not so much concerned with the composition of the material, nor theway it is fabricated, nor the preformed shape or dimension of the same, the present case having to do more with the means for anchoring the material with the rail so as to prevent dislocation. For this- -to interlock with means on the filler for anchoring the filler to the rail. In this conneotion I suggest that the rail be constructed with projections projecting into the space to be filled by the filler from' either the head, web or base thereof.

So far as the illustration in the accompanying drawing is concerned the underside of the head A is made with a projecting tip 5, and the top of the base B is likewise provided with a projecting tip 6. Theseprojections may be made on one or both sides of the flange C, and the preformed section of filler will be made with longitudinal grooves 7 along opposite edges so that when the filler is forced into the space in the rail the tips 5 and 6 will engage the grooves 7 and interlock therewith, as shown in Fig-' ure 3. This idea may be applicable to a rail having the customary flanged head A The section of filler is represented in all the figures as at 8. 4

The tips 5 and dare in reality continuous ribs and may be *prdvided for at the time the rail is rolled, or else they may be brazed thereon, or in fact otherwise provided for so long as a projection is made which will engage the filler 8 when interlocked therewith.

I claim:

1. In combination, a rail, a filler therefor said ffiller being substantially continuous with the rail and comprising a preformed bituminous block-like member having the inherent quality of compressibility, and

means for interlocking the filler with the rail, comprising meanson the rail projecting into the space to be filled by the filler,

said projection adapted to engage the filler and anchor the same to the mill 2. in combination, a rail havlng a head, base and connecting web with a space. be-

tween the head and base, and a filler for said ing the inherent quality of compressibility and means on the rail engaging with the filler for anchoring the same in said space.

3. In combination, a rail having head, baseand connectin web with a space between the head and base, and a filler for said space, said filler being substantially continuous with the rail and comprising a preformed bituminous block-like member having the inherent quality of compressibility, and means on the rail engaging with the filler for anchoring the same in said space, comprising a projection on the rail and a space in the filler made to receive and interlock with said projection.

4. In combination, a rail having a head, base and connecting web with a space between the head and base, and a filler for said space, said filler being substantially continuous with the rail and comprising a preformed bituminous block-like member having the inherent quality of compressibility, and means on the rail engaging with the filler for anchoring the same in said space, comprising a projection on the underside of the rail head, and a space in the top of the filler made to receive and interlock with said projection.

5. In combination, a rail having a head, base and connecting web with a space between the head and base, and a filler for said space, said filler being substantially continuous with the rail and comprising a preformed bituminous 'olock-like member having the inherent quality of compressibility, and means on the rail engaging with the filler for anchoring the \same in said space, comprising a pro ection on top of the rail base and a space in the base of the rail filler made to receive and interlock with said projection.

. 6. In combination, a rail having a head, base and connecting web' with a space between the head and base, and a filler for said space, said filler being substantially continuous with the rail and comprising a preformed bituminous block-like member haw ing the inherent quality of compressibility, and means on the rail engaging with the filler for anchoring the same in said space, comprising projections on the rail head and base, and spaces in the top and base of the filler made to receive and interlock with said rail filler comprising a preformed block-like" compressible member of bituminous material mixed with roofing scrap, said member having the inherent quality of compressibility. z 9. A preformed block-like strip composed of a mixture of bituminous material and roofing scrap, said strip being formed to fit between the head and base of a rail, and

said strip being so formed as to be readily compressible.
